What are the good methods for purchasing automotive parts products

How to choose the most suitable and cost-effective car parts? Here, we recommend the following tips to help you choose the best car parts: return and exchange if lost.
1. The packaging of original accessories is generally more standardized, with uniform standard specifications and clear and formal printing. However, counterfeit product packaging has relatively poor printing and can easily identify flaws from the packaging;
2. Some original accessories are specified with a certain color on the surface, and if other colors are encountered, they are counterfeit and inferior parts;
3. Look at the appearance of the original factory accessories with clear and formal printing or casting and markings, while counterfeit products have a rough appearance;
4. Illegal paint merchants manipulate waste parts through simple processing such as dismantling, assembling, assembling, assembling, painting, etc., and then sell them as qualified products, illegally obtaining high profits;
5. The materials used for the original factory accessories are qualified according to the design requirements, while counterfeit products often use cheap and inferior materials as substitutes;
6. Sometimes, although the appearance of a product is good due to poor craftsmanship, it is prone to cracks, sand holes, slag inclusions, burrs, or bumps caused by poor manufacturing processes;
7. If there are problems such as cracking, oxidation, discoloration, or aging when storing automotive parts, it may be caused by poor storage environment, long storage time, or poor materials themselves;
8. If there are phenomena such as loose rivets on the clutch plate, detachment of the brake leather tube, detachment of electrical component joints, or detachment of the paper filter element joints during the "engagement" process, it cannot be used;
9. Check if there are certain markings on the regular components in the labeling section, such as gear markings, piston top markings, and other assembly markings, to ensure correct installation of the parts. If there are no markings, they cannot be purchased;
10. Proper assembly components must be complete and intact to ensure smooth loading and normal operation. Some individual small parts on the assembly are missing, usually "parallel goods", which cause difficulties in loading. Often due to a shortage of individual small components, the entire assembly is scrapped;
11. To facilitate storage and prevent parts from being bumped, there is a protective layer on the parts before they leave the factory. For example, bushings, large and small bearing shells, pistons, valves, etc. are generally protected with paraffin to prevent surface damage. These important accessories, if not covered with a protective layer on the surface, are mostly "smuggled goods";
12. Some important components, especially assemblies such as carburetors, distributors, generators, etc., are usually accompanied by instructions and certificates of conformity when leaving the factory to guide users in installation, use, and maintenance. Without these, they are often counterfeit and inferior products;
13. When selecting car parts based on specifications, it is important to identify the main technical parameters and ensure that special technologies meet the usage requirements. Some counterfeit and inferior products have a similar appearance to the real ones, but when they are installed, they are not very suitable, either too big or too small, and they are always unsatisfactory to use, leaving hidden dangers of accidents.
14. A third-party inspection report can not only prove its authenticity, but also demonstrate its quality.
